Detection of flaws in brake pads with time and lower cost in the end-line.

The Challenge

The presence of flaws into the friction material or not a correct adhesion between it and the support may constitute serious problems for the safety of the vehicle. The brake pads consist of 2 components assembled together: the friction material and its metal support. They have two dynamic characteristics very different from each, specially, the first one is a material that is a material that tends to “soften” the vibrations. MaGyc has developed a system able to detect flaws such as inclusions, detachment from the support porosity (also not superficial) in brake pads, this solution can be used in the production line and cycle time reduced to seconds.

Solution

 Starting from the concept that every object is characterized by an infinite number of “vibration modes” which identify its dimensional and elastic feature,it is possible track any type of defect. In fact, similar objects will have the same frequencies, objects that instead have discontinuity or any type of defect, will have different frequencies which are identified by the system through an easy to use interface are visible to the user, in this way, the search for defects requires no bottlenecks in production, the defect has been detected thus contributing to a lower production cost for the company. The big difference of “damping” between the two constituent materials is resolved by performing numerous and repeated testing of each product concerned. The average of the results allows to obtain very reliable judgments of quality. The proposed solution allows to perform 5 repetitions in a total time of 500 ms guaranteeing, in addition to the reliability of the determination made, exceptional speed test.
